LELink was one of the first Bluetooth LE adapters supported by OBD Fusion for iOS. LELink has a very small footprint, and works with a variety of third party apps.
LELink is a good choice if you have space constraints when plugging into your OBD2 port. This adapter supports all legislated OBD2 protocols, but we have seen problems when connecting to vehicles using the J1850 protocol. If you have an older GM or Ford vehicle, you could experience connection issues.
